VIRTUAL REALITY Virtual reality (VR) systems create experimental environments with unlimited possibilities. They allow to investigate fundamental mechanisms of navigation, cognition, learning, or memory in animals. The VR allows flexible modifications of experimental environments and fast repetitions of simple tasks. The animal remains completely stationary while interacting with a virtual world. Animal activity can be correlated with external measurement data such as optical imaging or electrophysiology. Many different additional stimuli and reward systems may be added to make the VR more realistic and interactive. Standard mazes and experiments are provided that can be modified and extended according to specific experimental needs. Hardware synchronization and data export allow the easy integration with complex experimental setups The JetBall is an air cushioned spherical treadmill in combination with screens or a projection dome. It allows an animal to navigate and to perform behavioral tests in a virtual space, while it is examined by in-vivo imaging, optogenetic, or electrophysiological methods. The JetBall enables new applications in neuroscience. VIRTUAL REALITY VARIANTS The virtual reality is either displayed on a TFT surround monitor or via a spherical mirror projection to the inner surface of a section of a sphere. A common equipment rack integrates power supplies, control PC, and the air flow regulation system for JetBall and accessories. JetBall-TFT  Easy accessibility for external setups, e.g. microscopes and manipulators High contrast and luminance. TFT surround monitor with virtual reality scene (270°) with six 19“ sub-units Air cushioned spherical treadmill Ball holder Larger field-of-view for presenting the virtual reality Seamless projection surface. Dome (1.2m) with spherical mirror projection Air cushioned spherical treadmill Ball holder with stand Spherical mirror Projector PhenoSys GmbH. Schumannstr. 18. 10117 Berlin.
